DISAPPEARING WALL-BED.

Specification of Letters Patent.

To all whom- 1' 23 may concern:

die it known that I, HARVEY H. HALL, a citizen of the United States, residing at Denver, in the county ofDenver, State of Colorado, have invented certain new and useful Improvements in Disappearing Vall- Beds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it' appertains to make and use the same.

This invention relates to improvements in folding beds, and more particularly to that type known as wardrobe or disappearing wall beds, generally used in apartment houses, where the bed when not in use may be folded out of sight, and the bed room utilized for other purposes.

The primary ob ect of the invention is to provide a bed of this type, which will be more simple in construction, effective in action, and less expensive to manufacture than those heretofore proposed.

To these ends the invention consists in the novel details ,of construction and combination of parts more fully disclosed in the following specification, and particularly pointed out in the appended claims.

While the invention is not limited to the exact details shown and described, still for the purpose of disclosure, reference is had to the accompanying drawings illustrating a practical embodiment of same, in which drawings like numerals designate the same parts in the several views, and in which- Figure 1 is a view in perspective of the bed in its open position. Fig. 2 fragmentary sectional view taken in the plane of the line 2-2 of Fig. 1. Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2, and Fig. 4 is a detail diagrammatic elevational view, showing'a slightly different arrangement.

A pair of side walls 1 form a compartment for receiving and containing the bed in its folded position, and the side walls may be the sides of a wardrobe or the sidewalls of a recess formed in the wall of the room. The recess is provided with door-s2 for closing said recess when the bed is folded.

3 is a bed frame having at its outer end a suitable folding foot board l, the inner end of said bed framebeing peculiarly supported as hereinafter described.

The foot board or support does a part of the present invention,

not form but the erably Patented. May a, 1913.

manner of folding same may be briefly referred to. 5 designates a short link on each side of the bed disposed within the channeled rail and connected at one end to the foot board as at 6. The other end is pivoted as at 7 to the inside of the rail. 8 is a longer link on each side of the bed pivotally secured at 9 to the foot board and at 10 to the inside of the rail, so that when the bed, is to be folded the foot board may be swung around underneath same on the pivots 7 and 10.

Suitable weights 11 are mounted on the inner rail 12 of the bed frame.

13 designate guide-ways opposite to each other and located on theinside faces of the side walls. These .guideways, which are in the nature of slots, preferably extend on an incline upwardly and inwardly to a position substantially in alinement with the bed frame when opened, or for a height substantially equal to the height of the bed frame.

The upper ends of the guideways may preferably be provided with lateral slots 14, which form-a continuation ofthe upper ends ofthe inclining guideways, and while they may extend inwardly, are shown extending outwardly from the top thereof, preferably inclining downwardly at a slight angle. On each side rail of the bed, toward the inner end thereof, there is mounted a suitable projection or roller 15 engaging said guideways. These projections or rollers ride in the slots l3,the inclination of which tend to effect a downward thrust on the inner portion 16 of the bed, which assists in elevating the outer or longer portion thereof, and in the reverse direction of movement aids in retarding the lowering of the bed, as will be hereinafter referred to.

A pairof links 17 are pivotally supported at their lower ends, as at 18, and the supports 18 may be secured to the side walls 1, or to the fioor as illustrated. The upper ends of this pair of links are pivotally connected to a portion ofthe bed frame, prefto the side rails as being the most convenient parts. The links 17 are longer than the distance between 'the pivotal connection 19 and the rollers 15, so that in any position of inclination of the bed frame above the horizontal, a radius line from and of a length equal to the distance between 19 and 15, will always find a movable terminal position in the slot 13, preventing any binding of the parts.

Int-he drawings the upper of the 1 links 17, are shown not merely as pivoted to the side rails, but also slidingly engaging the san' 1e;20 designating short'yslots in which the pivots 19 ride. This construction is not essential, as the upper ends of the a. links 17 may simply be pivoted to thebed frame, but where the short transverse slots or guideways 14 are employed, the slots 2Q are provided to enable the bed frame to be slid 0utwardly,'when opened, in order that the inner end may besupported by the guideways or lower faces of the slots 14, against possible downwarddisplacement. From the detail diagrammatic view shown in Fig. 4,

- however, it will be seen that the slots 14 and 20 are not absolutely essential, because when the bed is in its open position, and

with the rollers 15 in .theupper. ends of the ever, to an extent causes a strain or stress on the pivoted rollers and the pivots 19 of the links 17, which is more or less overcome by the construction illustrated in Fig. 1 where the weight of the inner end of the bed frame is directly supported by the links.

and the rollers 15 resting in the transverse slots 14, and also preventing the bed from folding up of its own accord should a greaterweight be placed on the end 16 by the occupant or otherwise, an objectionable feature that has occurred in certain styles of folding beds, where the pivots 19 are located nearer the center of the bed frame.

Assuming that the bed is in its folded up position the links 17 will be in substantially vertical positions alongside of the bed frame. The inner rail may be transversely slotted to receive the links 17 when they are secured to the inside of the side rails. In this position the rollers 15 are in their lowermost position in the slots 13. Upon pulling out the upper or outer end of the bed the weights '11 will tend to counter-balance the weight of the major portion of the bed, from.

the pivots 19 to,th' outer end, and in addition to this the rollers 15 riding u the inclined slots 13, will help to retar the descent of the outer portion'of the bed. When the bed is fully lowered the rollers 15 are in the upper ends of the slots 13 opposite the transverse guideways 14. Up to this housing the bed the parts move in the .re-

verse order, and as the bed is elevated, the walls of the inclined slots 13, engaging the rollers 15, tend to, force the inner end 16 of the bed. downwardly and outwardly, and thus assist the counterbalancing weights 11 in compensating for the weight of the outer portion of the bed.

While the invention consists of the general construction and arrangement of parts as illustrated it will be obvious that the same is not limited to the exact details of con-- struction, ,and where I use the term rollers, it will be understood, forinstance, that their equivalent, such as pins or pintles may be employed to operate in the inclined slots.

What I do claim is i 1. The combination of a bed frame; a pair of swinging links slidingly connected at one of their ends to said frame; oppositely disposed guideways located adjacent the inner end of said frame and inclining upwardly and inwardly to a position substantially in line with the top of the bed frame when opened, and terminating in laterally disposed short slots; and projections carried by the inner end of said frame, riding in said inclined and transverse guideways and slots, substantially as described.

2. The combination of a bed frame having its inner end weighted; inclosing side walls for said frame; oppositely dlsposed slots formed on the inside faces of said walls and inclining upwardly and inwardly to a position substantially in line with the top of the bed frame when opened, and terminatin in short transverse slots slightly inclined downwardly; a pair of links pivotally supported at their lower ends below said inclined slots and slidingly connected at their upper ends with said bed frame; and projections carried by the inner end of said bed frame and operating in said inclined and short slots, the distance from said pr0- jections to said sliding connections'between the frame and said links, being less than the length of the links, substantially as described.-

In testimony whereof, I aifix my signature, in presence of twowit-nesses..
